Abstract

The ability of the conductance catheter method to measure left ventricular segmental and total volume was evaluated by comparison with the Cine-CT technique. In the seven dogs studied, 19 conductance catheter and simultaneous Cine-CT runs were obtained. High correlation coefficients were found for total volume and segmental volumes, except in the basal segment. However, in most cases there was a significant variability in slope and intercept between animals. Both methods are promising tools for estimating dynamic segmental left ventricular volume, each having specific advantages such as a continuous signal (conductance catheter) or anatomic detail (Cine-CT). However, the results also show the need for further improvement of both methods.
